Diodes Incorporated DMP4016SK3-13

Overview

DMP4016SK3 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in TO252 (DPAK) package, optimized for high-efficiency power management with 11 mΩ R_DS(ON) @ V_GS = −10 V, −75 A continuous drain current at T_C = +25°C, and fast switching performance. It serves as a synchronous rectifier or high-side switch in DC-DC converters.

For engineers reviewing the DMP4016SK3 datasheet, DMP4016SK3 pinout, DMP4016SK3 application, or DMP4016SK3 equivalent, key selection criteria include low R_DS(ON) at −4.5 V gate drive, robust UIS capability (−28 A avalanche current), and thermal resistance of 1.1 °C/W junction-to-case for high-power density designs.

Technical Context

This MOSFET employs planar trench-gate technology to achieve low on-resistance while maintaining controlled gate charge (Q_g = 112 nC @ V_GS = −10 V) and fast switching (t_F = 165 ns). Its body diode exhibits low forward voltage (V_SD = −0.7 V @ I_S = −1 A) and fast reverse recovery (t_RR = 27 ns).

The device operates across −55°C to +150°C junction temperature range and supports pulsed drain currents up to −300 A. Its SOA is characterized for single-pulse operation up to 100 ms with R_DS(ON)-limited DC boundary, enabling reliable use in transient-heavy power rails.

FAQ

What is the maximum safe operating temperature for DMP4016SK3?

The DMP4016SK3 has a specified junction temperature range of −55°C to +150°C. Its absolute maximum rating is TJ = +150°C, and thermal shutdown is not built-in-designers must ensure junction temperature stays within this limit using thermal modeling, copper area sizing, and ambient temperature derating per the transient thermal resistance curve (Figure 13).

Does DMP4016SK3 support logic-level gate drive?

Yes-its gate threshold voltage (V_GS(TH)) ranges from −1.5 V to −2.5 V, and it delivers 15 mΩ R_DS(ON) at V_GS = −4.5 V. This enables direct drive from −5 V logic sources or microcontroller GPIO with appropriate level-shifting, eliminating need for dedicated gate drivers in many medium-current applications.

Is DMP4016SK3 qualified for automotive applications?

The DMP4016SK3 is not AEC-Q101 qualified out-of-the-box. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-customers must contact Diodes directly to request AEC-compliant variants such as DMP4016SK3Q, which undergo additional qualification testing.

How is the exposed drain pad connected internally?

The TO252 package's exposed metal tab is electrically and thermally connected exclusively to the MOSFET's drain terminal. It must be soldered to a PCB copper pour tied to the drain net-not left floating or grounded-to ensure both thermal performance and correct circuit operation; improper connection risks thermal runaway or latch-up.
